/**
 * This example creates a new line item creative association (LICA). For small
 * business networks, creative IDs must represent new or copied creatives since
 * creatives cannot be used for more than one line item. For premium solution
 * networks, any creative can be used. To copy creatives, run
 * CopyImageCreatives.java. To determine which LICAs exist, run
 * GetAllLicas.java.
 *
 * Credentials and properties in {@code fromFile()} are pulled from the
 * "ads.properties" file. See README for more info.
